Higher derivatives #158

Closed rchristie closed 3 years ago

rchristie commented 3 years ago

Separate evaluation of derivatives from value with independent cache counters. Implement some direct higher derivative evaluations. Improved efficiency of cache validation during modifications.

Thanks Alan. FYI the main numerical operator derivative tests are already in the main codebase, see: https://github.com/OpenCMISS/zinc/blob/develop/tests/fieldmodule/numerical_operators.cpp Also some higher derivative tests here: https://github.com/OpenCMISS/zinc/blob/develop/tests/fieldmodule/field_operator_derivatives.cpp Add div of grad tested in TEST(cmzn_fieldmodule_create_field_divergence, grad_mag): https://github.com/OpenCMISS/zinc/blob/develop/tests/fieldmodule/create_derivatives.cpp
